Whoops!

Making fuel from corn produces only 30 percent more energy than it takes to produce the fuel itself, according to the government and corn industry sources (some are even more optimistic, claiming up to 67 percent net energy gain). But a study published in 2005 by Dr. Walter Youngquist, Ph.D., Emeritus Chair of the Department of Geology at the University of Oregon at Portland, said that “Ethanol is a net energy loss — it takes 70 percent more energy to produce than is obtained from the product itself.”

Inefficient.  This needs to be a pilot project until we get energy inputs down.   Algae is the likely efficient source of biofuel, but we are behind in the technology.
